Effects of salinity on sucrose metabolism during tomato fruit development

AbstractPhytochrome-mediated light and temperature perception has been shown to be a major regulator of fruit development. Furthermore, chromatin remodelling via DNA demethylation has been described as a crucial mechanism behind the fruit ripening process; however, the molecular basis underlying the triggering of this epigenetic modification remains largely unknown. Here, an integrative analyses of the methylome, siRNAome and transcriptome of tomato fruits from phyA and phyB1B2 null mutants was performed, revealing that PHYB1 and PHYB2 influences genome-wide DNA methylation during fruit development and ripening. The experimental evidence indicates that PHYB1B2 signal transduction relies on a gene expression network that includes chromatin organization factors (DNA methylases/demethylases, histone-modifying enzymes and remodelling factors) and transcriptional regulators, ultimately leading to altered mRNA profile of photosynthetic and ripening-associated genes. This new level of understanding provides insights into the orchestration of epigenetic mechanisms in response to environmental cues affecting agronomical traits in fleshy fruits.

A Cell

Before the onset of ripening, tomato fruit development comprises three distinct phases: fruit set, a cell division phase and a cell expansion phase. In this study, we used the method of mRNA differential display in order to isolate tomato genes specifically expressed during these early phases of fruit development. Among 40 differen-tial bands, nine cDNAs were selected for further investigations based on their identification after nucleotide sequencing. We isolated the full-length cDNA corresponding to one of these fragments, coding for RAD23, a protein involved in the excision repair system, thus providing new sequence information on a poorly characterised protein in plants. All the isolated cDNAs were mapped on the tomato genome and their expression studied by northern blot and semi-quantitative RT–PCR during early fruit development and in vegetative organs of tomato plants. The sequence data are deposited in the GenBank under the accession numbers: AJ270956 (mo5-3C11/1), AJ270957 (mo5-3G12/4), AJ270958 (mo5-3G17), AJ270959 (mo5-3T12), AJ270960 (mo1-6A1), AJ270961 (mo1-6T1), AJ270962 (mo5-10G1), AJ270963 (mo6-20G1), AJ270964 (mo6-MGT2) and AJ243875 (LeRAD23-8 full-length cDNA).
